How is it?

I have FP4, and while I really love it, and I’d buy another one in a heartbeat, there are compromises with respect to the competition.

On the other hand, I could clearly see that it was a massive step forward with respect to FP3, and that the gap compared to regular phones was shrinking fast.

So, again, how is it? How much of a compromise is it compared to a similar priced less ethical phone?
